The compressibility factor F is
rounded to 3 decimal places as
specified in the standard.
Equilibrium
pressure The equilibrium pressure is
considered to be 0 psig for liquids
which have an equilibrium pressure
less than atmospheric pressure (in

CTL Volume correction factor for
temperature.
Value will be rounded according to
input 'API2540 rounding' - CTL 1
CPL Volume correction factor for
pressure
Value will be rounded according to
input 'API 11.2.1 rounding''' - CPL 1
CTPL Combined volume correction
factor
CTPL = CTL * CPL - CTPL 1
K0 Actual value of constant K0 used
for CTL calculation - K0 0
K1 Actual value of constant K1 used
for CTL calculation - K1 0
K2 Actual value of constant K2 used
for CTL calculation - K2 0
Alpha Thermal expansion factor 1/°F ALPHA 0
F Compressibility factor - F 0
Product When input 'Product' is 'B - Auto
select', then the output is set to
the actual selected product of
table 5B / 6B (enumerative value
as defined for input 'Product'), else
the output is set equal to input
'Product'. - PRDCUR 0
CTL calc out of
range With respect to the standard used
for the calculation of CTL the
combination of input values is:
0: In Range
1: Out of Range
